We divide 161950 by 4
Our goal is to divide 161950 by 4.

Step 1:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 4

On to step 2:
4 goes into 16 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 16 from 16 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 4

On to step 3:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

On to step 4:
If we divide 19 by 4, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 404.0
Deduct 16 from 19 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 4

Moving on to step 5:
4 can be fit into 35 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 4048.0
Subtract 32 from 35 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

On to step 6:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 40487.0
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 4 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 40487.5
Subtract 20 from 20 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40487.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40487.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 40487.5 with a balance of 0.0.
